Configure I/O
Click the Configure I/O button to display the following dialog box.
Inputs
Enter the number of Input words up to a maximum of 240 words (480 bytes). The Start Address is
normally set to 0. You can change the Start Address to create an offset address. Different devices can
reference the same Interbus-S address but may require an offset for one of the devices. Changing the
Start Address will change the address ranges shown in the Interbus-S DP Protocol dialog box. The Start
Address is provided so that the user can align the tag address entered in Quick Designer with the
mapped address in the PLC or host device.
